Don’t be alarmed if you hear or see a number of helicopters flying over the East Cooper area today.

A helicopter aquatic rescue team is holding its quarterly training session at Isle of Palms County Park this weekend.

According to a release from the S.C. Emergency Response Task Force, helicopters should arrive at the park about 10:15 a.m. today and will be conducting exercises in the area until 5 p.m. On Sunday, the helicopters were expected to arrive at 9:30 a.m. and leave the park at 4:30 p.m.

The rescue team is a joint operation that combines helicopters and pilots from the S.C. Army National Guard and rescue swimmers from the State Urban Search and Rescue program.

This weekend’s training is to consist of practicing “lifting” victims from the ocean in front of the park and transporting them to a grassy area of the park. Organizers expect the training to be noisy.
